Things have changed since I was last in Ceos and Sothis. Only one Federation faction there, so data courier missions for Fed rank no longer work here. The alternative Chakpa and Ochosi are in the wrong state to generate courier missions right now. I guess its back to planet scan missions in the systems I was in before...Ugh.
My quest for Federation reputation missions for rank without data courier grinding has gone downhill in the latest system I'm based in. It's all planet scans for 5 rep+, so I'm just grinding those instead of data courier missions now. They require a trip to IF after each batch of 8 to 10 I do.
